The biggest difference was the reduction in rasp and low RPM volume. It was still loud enough when I got on the gas, hence, I was going to weld in this second one. Overall, I would say the tone was a bit more 'mature'. There's a time and place for loud exhaust. I was passed it. My mechanic removed the glass packed, and welded in the Vibrant in under an hour. I don't know too much about welding, but it held solidly for 3 years. No issues.
